AI Technical Summary

Technical Problem

Existing wireless communication systems face challenges in efficiently determining and transmitting resources for data and control information via uplink shared channels, particularly in 5G networks, due to resource shortages and high-speed service demands.

Method used

A method for a user equipment (UE) to receive configuration information for allocating resources on a physical uplink shared channel (PUSCH), map transport blocks to multiple slots, and multiplex uplink control information (UCI) with PUSCH, determining modulation symbols based on the scaled size or resource of the TB across slots, and using a predetermined redundancy version sequence for repetitive transmission.

Benefits of technology

This approach enables efficient resource allocation and transmission of data and control information, allowing for seamless multiplexing of PUSCH and PUCCH, and ensures efficient repetitive transmission of PUSCH even when initial slots are invalid.

Abstract

Disclosed is a method by which a terminal transmits a physical uplink shared channel (PUSCH) to a base station in a wireless communication system. The terminal can receive, from the base station, configuration information for allocating a resource for transmitting a transport block (TB) through the PUSCH, and map the TB to a plurality of slots constituting the resource on the basis of the configuration information. Thereafter, the terminal can transmit the TB on the plurality of slots through the PUSCH.
